No. Both foci are always inside the ellipse, otherwise you don't have an ellipse.

Two
It is a SPECIAL form of ellipse. In an ellipse the centre and the two foci are at separate points on one axid. In a circle the centre and the two foci are ALL at the circle centre.

No, and there are two of them!
False
An ellipse has 2 foci. They are inside the ellipse, but they can't be said to be at the centre, as an ellipse doesn't have one.
An ellipse, a hyperbola.
Foci.
As the foci of an ellipse move closer together, the eccentricity of the ellipse decreases. Eccentricity is a measure of how elongated the ellipse is, defined as the ratio of the distance between the foci to the length of the major axis. When the foci are closer, the ellipse becomes more circular, resulting in a lower eccentricity value, approaching zero as the foci converge to a single point.
